Symmetry- stupid question
Symmetry- stupid question
(OP)
Hi all,
I have a structure and I only model half of the structure due to symmetry. The structure is exposed to an impact of an sphere in the middle of the structure, this is modeled by a prescribed displacement of the sphere. . Due to this I only model half the structure and half the rigid sphere. If I want to know the reaction force on the symmetry line of the structure .. will the reaction force be twice the plotted reaction force that Workbench says because it is only half of the model? E.g. if workbench says 50 kN as the reaction force on the symmetry line will the actual reaction force on the whole structure be 100 kN?
Thank you

force of P on a 1/2 model is equivalent to 2P on the full model, 'cause the force is being applied along the plane of symmetry.

So, if the stresses of the full model and the half model is the same I suppose the strains are the same as well.. ? I dont have to multiply the strains of the half model by 2 in order to get the strains for the full model if I got it correctly ?

the internal loads between the two 1/2s are different (to the external load and reaction).
